摘   要： 增加結構保溫一體化墻體免拆模板的保溫層厚度可實現更高的節能目標 ，然而增加保溫層厚度，現有連接件不能很好滿足錨固要求 。本文提出適用于較厚保溫層免拆模板的連接件，對其連接性能進行分析，以實際工程為研究案例 ，通過ANSYS 將增厚墻體中的連接件替換成改良連接件，對一體化墻體 、加厚免拆模板  的整體性和改良連接件自身受力及變形情況進行分析 。經計算結果分析 ，一體化墻體整體錨固與改良前相比效果明顯，免拆模板與現澆墻體協調變形 ，改良連接件改進部位符合受力規律 ，穿出免拆模板背面產生的應力集  中不會對模板造成破壞 ，風壓增高的情況下錨固效果優于普通連接件 。結構保溫一體化墻體加厚免拆模板連接性能較好。

關鍵詞： 結構保溫一體化； 連接性能； 風載； 應力集中

Abstract:Increasing the thickness of the insulation layer of the structural insulation integrated wall removable template can realize higher energy saving targets, however, after increasing the thickness of the insulation layer, the existing connectors can not well meet the anchoring requirements.This paper proposes the connectors applicable to the thicker insulation layer free template, analyzes its connection performance, takes the actual project as a research case, replaces the connectors in the thickened wall with the improved connectors through ANSYS, and analyzes the integrated wall, the integrality of the thickened free template, and the improved connectors' own force and deformation.After calculating the results of the analysis, the integrated wall overall anchorage compared with the improvement of the former effect is obvious, no demolition template and cast-in-place wall coordinated deformation, improved connectors to improve the part in line with the law of force, wear out the back of the demolition-free template stress concentration will not cause damage to the template,   the wind pressure increases in the case of the anchoring effect is better than the ordinary connectors.The connection performance of the structural thermal insulation integrated wall thickening and non-removal formwork is better.

Keywords：structural insulation integration ; connection performance ; wind load ; stress concentration
